Windows to UNIX porting, Part 2: Internals of porting C/C++ sources
Part 1 of this series covered the typical C/C++ project types you work with in a Microsoft(R) Visual Studio(R) environment and introduced the processes of porting dynamic and static library project variants to a UNIX(R) platform. Part 2 delves into some of the compiler options used to build Visual C++ projects and the UNIX and g++ equivalents, takes a closer look at the g++ attribute mechanism as it relates to porting, and examines some common problems you might encounter while porting from a 32-bit Windows(R) environment to a 64-bit UNIX environment. It concludes with an overview of concepts for porting multithreaded applications and an example project that shows you how to pull all these pieces together.

AIX security reporting
Generating IBM AIX security reports should reflect the current security model overview of your system, and these reports can then be presented to managers or audit to show how your AIX system is managed with regards to security. In this article, I will demonstrate what type of attributes could be collected and why.

Avoid traps when porting Java Web applications from Windows to AIX
Examine three traps you could fall in when porting Java(TM) Web applications from Windows(R) to AIX(R), and learn how to maneuver around them. When developing applications, you normally do so in a development environment and then deploy to a production environment. If you develop on Windows and deploy to a UNIX(R)-like platform, you might encounter subtle pitfalls. The first trap sets up different line separators in Windows and AIX, the second shows the best approach to locate a file in different development environments and operating systems, and the third is a common exception in socket communication.

LDAP and the iPhone
A multitude of libraries have been written for UNIX systems. Many of those libraries have been released using open source licenses that allow a library's source code to be reused in new projects. By porting an existing library to a new platform, a developer may be able to save the time it would take to duplicate the development work to achieve the same functionality on the new platform. This is the first of a two-part article series on porting the OpenLDAP client libraries to the iOS. Part 1 walks the reader through the steps of importing the OpenLDAP source code into Xcode and building two static libraries for the iOS. Using the Xcode project created in Part 1, Part 2 will guide the reader through the creation a simple iOS application that executes basic queries to an LDAP server using the OpenLDAP libraries.

Port Fortran applications
Discover how to port Fortran-based High Performance Computing applications, such as computational fluid dynamic (CFD) modeling, weather modeling, and linear algebra packages, using IBM XL compilers and gnu compilers on large clusters. The solutions in this article are equally applicable in all types of porting work in Fortran or any UNIX(R)- or Linux-based systems. Though C/C++ and other programming languages are popular, with strong features and widespread use, Fortran is still the favorite for the scientific and engineering community because of its performance.

System Administration Toolkit: Monitor user usage
Explore new ways to record UNIX(R) logins and other system activities in a number of different logs, and take advantage of this information to monitor user usage. This can be helpful from a number of perspectives, either to use for chargeback reporting or just to get an idea of how busy and active individual users are on the system to help when planning and allocating resources.

Python testing frameworks: Selecting and running tests
The recent emergence of industrial-strength Python testing frameworks means that Python tests are being written more succinctly, more uniformly, and with better reporting of results than ever before. This article examines how the three most popular testing frameworks identify and gather tests, and what support they provide for writing entire layers of tests that share common setup and teardown code.

Python testing frameworks: Finding modules to test
The recent emergence of industrial-strength Python testing frameworks means that Python tests are being written more succinctly, more uniformly, and with better reporting of results than ever before. Here we look at how the leading testing frameworks provide robust auto-discovery of your application tests, and how this replaces the fragile central lists of tests that you used to maintain.
